Influence of PDTC on expression of LFA-1 mRNA induced with LPS in mouse non-specific keratitis reaction / 吉林大学学报(医学版)

ABSTRACT

Objective To analyze the relationship between leukocyte function-associated antigen-1 (LFA-1) mRNA expression and corneal inflammation and discuss the inhibition reaction of nuclear factor-?B(NF-?B)inhibitor on LFA-1 mRNA expression.Methods The corneal suture or combined with subconjunctival injection models were constructed in BALB/C mice.The corneas of each group were excised 1,3,7 and 14 d after operation and LFA-1 mRNA expressions were investigated by reverse transcription polymerase chain reaction(RT-PCR).Results At 1,3 and 7 d after operation, the expressions of corneal LFA-1 mRNA in corneal suture combined with lipopolysaccharide (LPS) (corneal suture+LPs)subconjunctival injection group were higher than those in corneal suture group (P0.05).At 1 and 7 d after operation, compared with corneal suture+LPS group ,the expression of corneal LFA-1 mRNA increased,but it decreased at 3 and 14 d after operation in the group of corneal suture combined with LPS and pyrrolidine dithiocarbamate (PDTC) (P
